Just one question - if I'm going to do darks, should I turn off the noise reduction in my camera?

Yes.
There are couple of reasons for taking separate darks:
- Taking separate darks and stacking them in DSS results in slightly better SNR for the same number of stacked frames.
- LNR takes twice the time (for example, if you are taking 30 sec exposures (lights), camera will take another 30 sec for LNR compensation for each frame).
Please note, you should take the same exposure time for darks. But it can be done later, and you do not have to take as many darks as lights. Some people will say you should take the same number but this is not my experience). They should be taken at same temperature, though.. best immediately after your photo session.
